摘　　要：塑件浇口位置的设置关系到熔体在模具型腔内的流动,并从而影响聚合物分析的去向和塑件成型后的翘曲。以开关按钮为例,建立了不同浇口位置的模型,借助Mold Flow分析软件对各方案进行分析,通过对模拟结果的分析对比,总结浇口位置对塑件翘曲变形的影响,并进行了浇口方案的优化。The setting of gate location of plastic pieces is related to the flow of the melt in the mold cavity, the whereabouts of the analysis of the polymer,and the warpage of the molded products. In this paper, exemplified by the switch,we establish the different gate locations of the model and analyz each program by MoldFlow software, summariz the influence of gate location to the warping deformation of plastic through analysis and comparison of the simulation results and optimiz the scheme of gate location.
